tion, coming within the scope of the appended claims.

I claim:

1. In a valve for internal combustion engines, a valve casing formed with a passage, a tapered Valve seat through said casing, a tapered valve having an opening extending diametrically therethrough, said valve adapted to be oscillated to open and close the valve passage, yieldable means for holding said valve upon its seat in a position to close said valve passage and at the same time act to yieldably resist rotary and lateral motion of said valve, means for oscillating said valve to open and close said passage and means co-operating with said oscillating means whereby said valve is retracted from the seat prior to advance rotation of said valve and whereby said valve is returned to its normal position before it is advanced laterally in said casing to return to its seat.

2. In a valve for internal combustion engines, an engine cylinder, a head therefor formed with a passage opening to said cylinder, a tapered valve extending longitudinally of said passage and turnable in said head on an axis extending transversely of the cylinder, said valve being adapted to be removed and replaced from the side of the head, a spring encircling one end portion of said valve affixed at one end to the valve and at the other end to the head, said spring exerting a longitudinal pull on said valve and yieldably opposing turning movement thereof, and means for oscillating said valve.

3. In a valve for internal combustion engines, an engine cylinder, 21- head therefor formed with a passage opening to said cylinder, a tapered valve extending longitudinally of said passage and turnable in said head on an axis extending transversely of the cylinder, said valve being adapted to be removed and replaced from the side of the head, a spring encircling one ,end portion of said valve affixed at one end to the valve and at the other end to the head, said spring exerting a longitudinal pull on said valve and yieldably opposing turning movement thereof, and means for oscillating said valve and means operating on oscillation of the valve to move the valve longitudinally in opposition to the spring on the advance stroke of the valve and permitting retraction of the valve under action of the spring on the retrograde stroke thereof.

4. In a valve for internal combustion engines, a valve casing, a tapered valve seat in said casing, adapted to have both longitudinal and rotary movement, a spring connected to said valve and acting to oppose its turning in one direction and opposing its longitudinal movement in one direction,

means for oscillating said valve, and means acting on turning the valve in one direction to move it lengthwise in opposition to said spring adapted on turning the valve in the other direction to permit restoration of the valve by said spring.

5. In a valve for internal combustion engines, a valve casing, a tapered valve seat in said casing adapted to have both longitudinal and rotary movement, a spring con nected to said valve and acting to oppose its turning in one direction and opposing its longitudinal movement in one direction, a disk pivoted on said Valve, means for oscillating said disk, means whereby turning said disk will efl'ect turning of the valve with lost motion of the disk at the termination of the strokes, and means acting on said disk for efiecting longitudinal movement of said valve in one direction.

6. In a valve for internal combustion engines, a valve casing, a tapered valve seat in said casing adapted to have both longitudinal and rotary movement, a spring connected to said valve and acting to oppose its turning in one direction and opposing its longitudinal movement in one direction, a disk pivoted on said valve, means for oscillating said disk, means whereby turning said disk will eflect turning of the valve, a cam recess on said disk, and a roller on said valve casing extending into said recess when the- JOSEPH W.

WHEELED PLOW.

Application filed. August 16, 1919. set-a1 No. 317,910.

T 0 all whom it may concern Be it known that Trrnorr-IILUs BROWN and CARL G. STRANDLUND, citizens of the United States, residing at Moline, in the county of RockIsland and State of Illinois, have invented certain new and useful Improvements in l/Vheeled Plows, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to wheeled plows and more particularly to that type which may be either tractor or team drawn, and the object of our invention is to provide means for a quick and effective change in some of the parts whereby the plow can be adapted to attachment to a tractor, or fitted with a pole for draft animals, as will be more clearly set forth in the following specification.

Referring to the drawings in which similar numerals indicate identical parts- Figure 1 is a plan view of a wheeled plow embodying our improvements. 7 r v Figure 2 is a front elevation of Figure 1. Figure 3 is a detail side elevation of the furrowward side of the implement showing the manner of supporting the furrowwar-d beam on the axle. V

Figure 4: is a detail in elevation of the landward side of the implement, andthe means employed to raise the plows from the ground.

Figure 5 is a detail section on the line 5-5 of Figure 1, and

Figure 6 is respective detail view of the furrow wheel axle bearings. I

The frame of the implement consists of plow beams 1 and2 rigidly connected by braces 3 and 1, and beam lconverging, at its forward end toward the beam 2; the forward ends of the beams hold between them a clevis 5 to which the beams are rigidly secured.

This clevis may be of any one of several well known types suitable for connection to a tractor. On the rear of each beam is mounted a plow body 6.

The frame 1s supported on a crank axle 7,

rockably journaled in a bearing 8 on the beam 2. The landward end of the axle 7 is bent downwardly substantially at right angles and terminates in a portion-9 extending inwardly toward the beam 2 and having mounted thereon a landwheel 10. The furrowward end of the axle 7 is also bent downwardly and terminates in an outwardly .extending horizontal portion 11 on which is a sleeve 12. r

Preferably integral with the sleeve 12 is a vertical sleeve 13 in which is journaled a vertical spindle 14 having itslower end bent outwardly to form an axle .15 on which is mounted the furrowwheel 16; the axle 15 is inclined as shown to give proper inclination to the furrowwheel 16 when the latter is in a furrow and the implement is horse drawn as illustrated. The upper end of the spindle 14 is a tapered square .17 on which is mounted a horizontally operating lever 18 having. a square tapered socket to receive the upper end of the spindle 14 which isreduced 1n size at. its termination and is threaded, the threaded end'passes through an opening in the socket of the lever 18 and is provided with a nut19 to ;hold the lever 18 securely in place. Pivotally mounted on the spindle. 1%1 below the lever 18, is a casting 21 having preferably integral therewith a horizontally disposednotched. segment 22 extendingland wardly with the lever 18 and adapted to be connected to the latter by a dog 23 on the lever 1 8 .QA draft tongue2 l is rigidlymounted on a forward extension 25 of the casting i i V before stated the frameis supported on a crank axle7, which is rockably .jour-.

naledina bearing 8 on the beam 2 onthe beam 1 is aswi-nging bracket 26 in which isrockably' journaledthe furrowward por tion' -of the crankoaxle 7,.the bracket 26 is swingable; by a lever 27 rigidly: attached theretoandlprovided with the usual type of latch to engage with a notched quadrant 28 mounted on the beam 1, this mechanism is operative to level the plow, and is moreclear ly and fully described in the application of Carl Gr; Strandlund, filed August 8, 1918, Serial No. 248,993, and to whichr eference is made for further description.

The crank axle 7 is rockable to raise the plows out of operation or to lower them
